Sigma Lens Upgrade (not)

[rodbunn]

Just to let everyone know, I called Sigma and told them my 22mm 2.8 didn't work with my 10D and they said that that model is discontinued and they can't fix it. Then they tried to sell me a 24mm for $240 IF I TRADED in the 22mm..... Why would I do that? My 22mm works fine with my A2's, why not just buy a new CANON lens and keep my old Sigma too.....

Anyway, just thought I'd let everyone know Sigma IS NOT fixing ALL the lenses.

Could you tell us the approximate age of the Sigma lens? Manufacturers do have to discontinue products after a certain time.

Hi, it's about 8 years old (I think)..... The thing is it works perfect with my A2's so I would think if I bought a new A2 it would work with it.

I think I'm having problems with the apateur not working on my newer Sigmas. They are 3-4 years old and it looks like the 10D isn't able to control the apateur. I'm going to call Sigma again and see if that is a problem with the 70-200 2.8 and the 28-70 2.8.....

Later, Rod

I have the Sigma 70-200mm/2.8 HSM lens.
It works perfect on my 10D


Sigma has a list of lenses that cannot be upgraded.

Most can, but some of the cheaper original AF lenses cannot.
